Question

Why solubility of sodium hydrogen carbonate decrese during solvay process?

Answer 1

One of the raw materials for the process is limestone (calcium carbonate, CaCO3). Limestone is heated to produce carbon dioxide. The carbon dioxide is dissolved inwater. ... When NaCl is added to aqueous NH4HCO3, a precipitate of sodium hydrogen carbonate, NaHCO3, forms
